Application filed. Silly Z l To all whom z' may concern:

Be it known that we, BERNARD T. Mnsiink and Camussi". E. Sinin, citizens ot the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useul `improvement in Metallic Window Constructions, oi which the following is a Jfull, clear. and eXact description, such as will enable others skilledin the art to which it appertains to make and use the sam reference being had to the accompanying drawings, forming part of this specification.

This inventionrelates to metallic building structures, and more specifically to hollow metal frame and sash construction for wall openings.

For the purpose oi? illustration and olisclosure, we herein show and describe a window trame and sash construction, although it is obvious that the invention is not confined to wincow construction, but is equally applicable to door, skylight, and other constructions. v

The-objects oi' this invention are to provide a tire proof or tire retardant construction which will be strong and rigid and which will retain its shape andintegrity when subjected to high temperatures such as would be occasioned by tire; to provide such a structure which may be completely 'fabricated in a shop and shipped in knockeddown condition, the construction being such as to enable the rapid, accurate and facile assembling oit' the structure by a mechanic at the place et installation; to do away with the necessity for riveting in the assembling of the structure; and to reduce 'the cost of construction.

@ther objects contemplate the provision of a hollow metal trame and sash construction in which the joints or seams are so disposed as to be most Vtully protected Pfrom weather, and also to provide a construction wherein external joints are so devised as to obviate the necessity ot soldering the edges of the sheet metal 'for the purpose oi weather protection, our construction being of such nature that all external joints and edges are `fully protected from weather and corrosion when painted.

Other and further objects will be obvious or hereinafter pointed out.

Specification of Letters Patent.

TH, OF ST. LOUIS, MISSOUR'T, ASSIGNGRS TO ST. LOUIS, MISSOURT, A CORPORATION OF Paten-tool Jan. 6, 1920.

916. serial No. 107,942.

For the purpose of illustration, we have shown in the accompanying drawings a window of the double hung type with vertically sliding sash each ot which is counterbalanced by its own system of weights and suitably glazed.

ln said drawings,-

Figure 1 is an elevational view lot the inside or chamber side of a window frame and sash of our improved construction.

.Fig 2 is a fragmentary detail of the various members insection on line 2-2 ot Fig. l, the various portions thereof being broken away. Y

Fig. 3 is a perspective showing the upper 'end oi'f one of the vertical trame members.

Fig. l is a perspective showing the end et the head member of the frame.

Fig. 5 isa vertical section substantially on line 5-,5 of Fig. 2. y

Fig. 6 is a perspective showing the corner construction et the sash.

Fig. 7 is a detail illustrating the method oi? securing the head frame .member to the jambe.

Fig. 8 is a horizontal section approximately on line 8-8 of Fig. 2.

Fig. 9 is a horizontal section approximately on line 9 9 of Fig. 2.

Fig. 10 is a horizontal section approximately on line lll-l0 o1 Fig. 2.

1l is a sectional detail illustrating the connection between a stile or rail member and a muntin.

Fig. l2 is a section oi' the same construction approximately on line lQ-lQ of Fig. ll.

13 is a cross section olf the muntin.

Byret'erence to these drawings, it will be seen that the 'trame is made up of a sill l, a lintel or head 2, and jambs 4. The sash is made up oil? rails stiles 6, and muntins 7. These members are all made up oi sheet metal parts suitably shaped and secured together. Y j

The head or lintel, as will be best seen in Figs. 2, 4 and 5 and 8 is made up of a hollow rail 8 and top member 9. rlhe rail is shaped to to-rm the lintel tor the traine and side portions extending up therefrom. Its upper edges are turned over to torno hook members l1 which are adapted to interenwith similar hook members 12, on the top member 9 whereby' to secure the two head members together, the top member eooperating with the upper edges of the lintel member to hold them properly spaced apart, and form a closure and the tourth side oi' .5 the head member. The top member 9 is slid into position. on the lintel troni. the end. The lintel is sli psd to pro ide a Weather n 11it'or the sa h and is pierced with slots for the passage the pension chain-.1.. .fl-it the ends the lintel is piovided with extending lugs i5, the ends ot which are bent laterally and inclined so as to provide beveled inner faces.

The jam'bs, as will be best seen in Figs. 2, 3, 5, and 7 to l0 inclusive, are made of tivo pieces, one forming the face, sides and back, and hereinafter referred to as the face piece 1.7, and the other being a :removable stop strip 18 Which is secured to the face of the jamb With screws 19 (see particularly Figs. 9 and 10), the stop strip 13 terminating at the bottom ot the head member 8. The Jface member l? is provided With apertures 2l through which the lugs 16 of the lintel are adapted to pass when the jamb and head are disposed in assembled relationship. n the inner sides of the face member 1"(V are slidable plates 22, from one end of each of which projects a pair of locking Wedges 24 which `are adapted to engage the beveled inner faces on the laterally turned ends oi the lugs lf3. When driven into engagen'ient with the lugs i6, the Wedges 2e on locking plate will draw the lintel nrmly e t the Ylace niember forming a very rig butt joint. The top r' aber 9 when slid into L,a gement with the`r ,lintel and against the end of the amb, liliewise stil-lens the joint between the lintel and jamb members.

ported the spindle 2S, carrying the chain a s 29; he sheaves project through es in the face member above the oi the lintel. Below bracket 25 the 's divided into two compartments by a p `=tition member 33 which is secured in place by small extensions 3l which are projected through slots in the outer portion oi the face member, and then turned over on members 38. Above these Wedge members,

y except in the portions e0, and weather lock el. ln the case of the top and bottom rails the Weather lock is opposite the glass groove, While in the ease of the meeting rails it is formed on the side (see Fig. 2) in the ease or' the top and meeting rails the ends of the rails overlap the stiles, While in the ease ot the bottom rail, the ends oi the rail abut'the stiles. joints between the rails and stiles are square groove Where the joint is mite-redL as shown at M in Fig. 5. The stiles are each made of one piece of sheet metal shaped to form the groove, sides and back. rllhe seams in the rails and Stiles are in the form of hoolrjoints d which are disposed along the bottoms ot the glass grooves, in which positionsaid seams are completely protected from the Weather, both y their interior position, and by the putty with which the glass grooves are lilled When the sash. is installed. The back is shaped to form the flange 4:2 which engages the amb to bold the sash in place. At their meeting extremities the rails and stiles are provided with joint members le secured in place by rivets 45 and provided with registering tongue i6 and groove 47. These joint memare U-shaped so that a registering tongue and groove is provided on each side. llfhen the rails and stiles are placed together in assembled position, the engaging joint members and the side portions prevent sliding displacement and a bolt 49 inserted through a suitable aperture in one of the joint members and threaded into the coperating joint member, is employed to draw and clamp the rails andV stiles firmly together. ln the ease of the meeting rail of the lorver sash, these bolts 4&9' are eye bolts or hooks to provide attachment for the suspension chains 50, as best illustrated in Fig. 2. These chains pass over the sheaves 29 and carry suspension Weights 5l which operate Within the compartments ot the amb. The znuntins, as Will be best seen in igs. ll to 13 inclusive, are each made of one piece of sheet metal which is shaped to form face portions 52 and intermediate oppositely dis posed glass grooves, the seam, as in the ease of the rails and stiles, being disposed along the bottom of one of the grooves.`

Rivets 5dpassing through spacers 55 are disposed at intervals 1n the bottoms ofthe glass grooves so as to provide stlienlng and forming the glass The llG

strengthening connections, and other rivets 56 passing through spacers 57 secure the face portions 52 together' at intervals, said rivets extending transversely of the rivets 54. At the ends of the muntins a plate 58 is in serted, the same being formed to fit over the groove-forming members of the rails and stiles and to project into the glass slot. These plates S are secured to and between the face portions 52 by rivets 59 and 60. The muntins are secured to rails or stiles by the screw 61 seated in the groove portion of the rail or stile and in the plate 58.

From the foregoing description, it will be seen that the various members of the frame or sash, such as the jambs, head, sill, rails, stiles and muntins may be made complete in proper size in a factory, and shipped in knocked-down condition. When it is desired to install the structure, the frame is quickly and easily put together by fitting the jambs to the sill by means of eye members 34 and locking plates 37, as above described; then assembling the sash by connec-ting the lower rails, stiles and muntins,

as above described, sliding the glass into the glass grooves and then applying the upper rails and securing them in the manner described. Thereupon, the sash are slid into their proper grooves in the jambs, the suspension chains and weights rigged and finally the head 9 placed and secured in position to close the frame. Thereupon, the frame may be set in the masonry.

The frame and sash, as thus constructed, while susceptible of quick and easy assembling, is exceptionally strong and rigid. Furthermore, it provides a superior fire proof and fire retardant closure. The flange and groove interlocking construction between the frame and the sash, and between the meeting rails provides close ire locks along the lines of separation. The sash may be easily removed for reglazing by removing the bolts 19 and taking out sash stop 18 along with the lower sash, thus permitting the removal of the upper sash. Furthermore, the structure is water tight, particularly if red lead is applied at the joints when assembling, and the structure presents a graceful and pleasing appearance. All of the joints which are externally eX- posed, such as the joints between rails and stiles, between muntins and rails, and between the vertical and horizontal members of the casing, are close butt joints, the edge of the metal on one of the joining members abutting the edge of the metal on the other. Thus the joint presents a perfectly smooth exterior surface, which may be smoothly painted, and which when so painted is fully protected from the weather. In this fashion, soldering of these joints along the edges of the metal for protection from weather, as is necessary in the case of lap joints, is oloviated.

tions are provided with beveled shoulders,

and wedging means slidably mounted within the apertured member and movable into engagement with the beveled shoulders on said projections whereby to draw said members v together and secure them in assembled relationship.

2. in a structure of the class described, hollow members arranged with the end of one member abutting a side of the other member, said members being provided with registering projections and apertures, said projections being provided with beveled shoulders, and adjustable wedging means mounted within one of said members and movable into engagement with the beveled shoulders on said projections for the purpose of drawing and securing vthe members together.

3. Tn'a structure of the class described, the combination of hollow abutting members, one of said members being provided with wedge members mounted. movably therein, the other of said members being provided with projections having beveled shoulders adapted for engagement by said wedge members for securing the members together in abutted position.

Li. 1n a structure of the class described, the combination of hollow abutting members, the wall of one of said members being provided with apertures, a plate mounted for sliding movement within the apertured member, wedges on said plate, projections on the other one of the hollow abutting members, said projections adapted to be inserted through the apertures in the other member, and said projections being provided with inclined shoulders with which the wedges on the sliding plate are adapted to engage.

In testimony whereof we hereunto a'iix our signatures in the presence of two witnesses, this third day of July, 1916.
